AMS 5663 is a 718 Inconel.
All that we have learned with ceramics is with hardend 625.
http://www.indmetal.com/productslist.asp?m...m=Bar&cmd=reset
The iron content in 625 makes it a different animal than 718.
I have found that milling the 625 with ceramics takes some effort to find the sweet spot. It may be a little easier with the 718.
At the time I spoke with Sandvik and Ingersoll, I was given the parameters for 718, (it was all they had test data for in the Inconel)
3300 SFM
.08 MAX DOC
.004 CPT
Sandvik stated a 3-4 minutes life per edge.
Ingersoll stated 4-6 minutes life per edge.

I found when cutting the Ni materials by lowering the SFM and raising the Feed, i was getting better tool life and make a good chip.Dead on trumper777
I ended up running 550 SFM, .08 DOC, .010 CPT.
2" facemill 4 inserts 1051 RPM @ 42.0 IPM.
We went from 4 hours 20 minutes CHIP TIME on two machines(carbide) to 48 minutes CHIP TIME on one machine.
Rob,
Absolutely dry.
Break your toolpath to run for the planned failure (3-4 minutes of chip time per edge).
You should also tweak your toolpath for very smooth transitions into the cut.
In our application, I had found that trying to ramp with a mill did not gain enough tool life for the effort.
I would keep a fire extinguisher handy.
Expect to see something like this.

Thad,
If it would help, I would be glad to fax you those pages from my Tosnuc book. It shows equations using Q,K, & L. Not sure how it works,
I've never used it.
Chad,
I have to wonder if we are serving the same customer. We just ran cylindrical and hollow
718 Inconel parts. Also 4th axis rotary. Ours are 6” dia. We made a steel arbor for the part to slip fit.
Used a nut on the end and also used the tailstock. We used 3/4" Guhring Firex coated rougher.
Mark is real close to where we ended up, we ran 100 sfm @ .0013 cpt with .235 doc.
Water soluble coolant was not a problem. I went the route of the ball mill to re-create
An O.D. but it proved to be very time consuming. Tolerances allowed me to use a standard 3/8”
Carbide endmill doing a 3D contour with .100 stepover.

Ok. What are the benefits of having dual monitors?
In a nutshell, how many times do you alt+tab
in a day?
I, like so many others, run mcam on one and cimco
editor on the other.

Since installing X, I've also experieced
the same lagging problems with V9 as Joe and
Dan stated above.
X would crash often.
Check out the response from gcode
http://www.emastercam.com/ubb/ultimatebb.p...ic;f=1;t=020639
I changed the settings to "best performance"
V9 no longer lags, and I have yet
to crash X.

Look at where your canned text outputs are defined. I've seen this previously in my own posts and it was caused by a syntax error in how I typed the output.Not sure if this is what you mean, but this is in my post;
strcan1 "(FIXTURE NO. ON ANGLE PLATE)"
strcan2 "(HOLD PART IN FIXTURE NO. ON TABLE)"
strcan3 "(HOLD PART IN 3-JAW CHUCK ON TABLE)"
strcan4 "(HOLD PART IN 3-JAW CHUCK ON ANGLE PLATE)"
strcan5 "(G54 X0 Y0 = C/L OF PART)"
strcan6 "(G54 X0 = DATUM -?-)"
strcan7 "(G54 Y0 = DATUM -?-)"
strcan8 "(Z0 = TOP OF PART)"
strcan9 "(Z0 = C/L OF PART)"
strcan10 "(G54 Y0 = EDGE OF TABLE)"
I make my selection through toolpath parameters/
canned text. I don't type anything in.
It worked in V9, that is why I wouldn't
suspect syntax.
Thanks for the quick reply
From canned text options, I make my selection / selections.
Whether I select 1, 2, or 6 different canned text options,
the post always outputs 10 lines of text. The last selection
made will be duplicated to make a total of 10 lines.
This happens with all of my Mach. Defs.

Any help would be appreciated
Thanks

what's the matter, don't like coolant getting hosed into your changer?

Thanks guys
I'll have to give that a try a little later, the boss wants to see me right now.
Maybe the coolant got on the boss.
Lou,
I neglected to say that you CAN still
use Cimco as your editor, just disable
the NC-Base side of it in;
setup / global setup / general tab.
I did this and Cimco now
opens in a flash.

Couldn’t get back to you yesterday, X seminar.
What you have here is the same thing I have.
pcoutrev #Rotary axis revolution calculation (Modify for wind-up)
cdelta = csav - prv_csav
while abs(cdelta) > ctol, #If motion exceeds ctol, add wind-up
[
if cdelta > zero,
[
rev = rev - one
cdelta = cdelta - 360
]
else,
[
rev = rev + one
cdelta = cdelta + 360
]
]
if cuttype <> one, cabs = rev * 360 + csav
else, cabs = sav_rev * 360 + csav
!csav
As DaveR stated above, you need to look
for Rotary Axis Settings
(in the post I use, it is on line 178)
one_rev : 0 #Limit rotary indexing
between 0 and 360? (0 = No, 1 = Yes)
I have one_rev : 1
one_rev : 0 will allow the rotary to go beyond 360°
one_rev : 1 will force the rotary to UNWIND to the next “B” or “A” position.
Not sure if this is exactly wat your looking for.
That is how it works for me.
